Application filed August 4,1906. Serial No. 329.221.

Patented Dec. 25, 1906.

To all whom it may concern:

Be it known that I, HANS ANDERSON, a citizen of the United States,residing at Crystal, in the county of Pembina and State of North Dakota,have invented a new and useful Cultivator, of which the following is aspecification.

This invention has relation to cultivators; and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a cultivator having adjustableside blades which may be used either for cutting weeds or for agitatingthe soil and are susceptible of adjustment into positions to performeither operation stated. The said cultiva tor is also provided with anattachment which may be used for the purpose of harrowing or pulverizingthe soil.

Various novel features of adjustment will appear as the invention isexplained in detail.

In the drawings, Figure 1 is a top plan view of the cultivator. .Fi 2 isan end view of the same. Fig. 3 is a si e elevation of the forwardportion ofthe beam of the cultivator with parts broken away.

The cultivator consists of the beam 1, which is provided at its forwardend with a clevis 2 and the colter-wheel 3. The crossbars 4 arecountersunk into the upper and lower edges of the said beam and aredovetailed therein. The forward ends of the wings 5 are pivoted betweenthe ends of the cross-bars 4. A wing 5 is located on each side of thebeam 1. Theplow-standards 6 are mounted upon the said wings 5 and carryat their lower ends the plow-shovels 7. The toggle-links 8 are pivotedto ether at their inner ends, and the outer en s of said links arepivoted to the beam '1 and the -win s 5, respectively. The links 9 arepi otal y attached to the intermediate pivotal points of thetoggle-links 8, and the working ends of the lever 10 are pivotallyattached to The said lever 10 is in turn fulcrumed upon the beam 1. Thestandard 11 de ends from the forward portion of the sai beam 1 and isprovided at its lower end with the horizontallydisposed blade 12. Therear edge of the said blade is provided with the recesses 13, each ofwhich is provided at its inner ed e with the tongue 14, which dividesthe sai recess into horizontally-disposed portions and the inclinedportions 16. Theunder surface of the blade 12 is slightly concaved, asat 17. The standards 18 depend from the rear portions of the wings 5 andare provided at their lower ends with the horizontal extensions 19.

The blades are pivoted at their forward ends in the recesses 13 of theblade 12 and are provided at intermediate points with the sleeves 21,which receive the portions 19 of the standards 18. The forward ends ofthe said blades 20 may' be located in the horizontal portions 15 of thesaid recesses 13 or in the inclined portions 16 of the said recesses. Itis obvious that when the forward ends of the said blades 20 are in theportions 15 of the said recesses 13 the said blades will be inhorizontal positions and that when the forward ends of the said bladesare in the inclined ortions 16 of the said recesses 13 the said bladeswill be in inclined positions. In eitherv instance the forward ends ofthe said blades are pivotally connected with the blades 12. The harrowmember 22 is pivotally attached to the rear end of the beam 1. Saidmember 22 preferably consists of a piece of sheet metalv having theteeth 23 formed at its lower edge. adapted to pulverize the. soil. Thelever 24 is fulcrumed upon the beam 1 and is connected by means of thelink 25 with the said harrow member- 22. By the manipulation of the saidlever the an le of inclination of the harrow member 22 with relation tothe beam 1 may be adjusted and varied. By the manipulation of the lever10 the an le of inclination of the toggle-links with re ation to eachother may be varied in order to spread the rear ends of the wings 5 orto bring the same together. When the implement is intended to be usedfor cutting weeds, the blades 20 are adjusted in their horizontalpositions and when it is intended that the said blades should cut thesoil they are disposed in inclined positions, as above described. Theforward ends of the handles 26 are attached to thebeam 1, and the owerends of the levers 10 and 24 are locate between the said handles and arewithin easy access of the plowman.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is.

An implement such as described comprising a beam, a standard attachedtothe beam,

The said teeth are said standard and being ivotally attached my own Ihave hereto aflixed my signature in the presence of two wltnesses.
